Piezo and photoelectric coupled nanogenerator using CdSe quantum dots incorporated ZnO nanowires in ITO/ZnO NW/Si structure

► Fabricated an unique sandwich type ITO/n-ZnO NW/p-Si nanogenerator. ► Simultaneous harvesting of both light and mechanical energy achieved. ► CdSe incorporation with ZnO nanowires increased the performance of the device. ► First report integrated both nanogenerator and solar cell in a same surface. ► Incorporating nanoantenna this structure can harvest light, heat and sound.
